yes, quite a dangerous mine also bad air in one spot and very unstable false floors. The mine originally went much further under the village of brewster but is now inaccesable due to dirt blocking the drift that runs parallel with the stope it apears there was a shaft there that was filled. There is another access point from from the basement of the building that used to be a hotel, i think the building is the currently a flower shop across from the train station. I interviewed a construction worker who said that when the drainage tunnel was redone they intesected mine workings and that before the precast concrete tunnel sections were installed about 20 years ago the mine was accessable this way. I also interviewed someone who used to live in brewster who said a shaft opened up in his back yard. If any one has any information on the Brewster mine also known as the Cheever and Durant iron mines please feel free to share
